This spout preferably into operative position'for use in connection extends L upwardly from rthe bottom of the with either bowl. v container from a point adjacent the topv 30 A further object of the invention is to thereof and thence downwardly and out 89 provide such'a device which is adapted'to wardly. The diaphragm G comprises a beattached to the upper end of the support flexible annulus- 15 of rubber or the like, whereby the container may be swunginto the peripheral edge of which overlaps the either an operative or inoperative position upper-end of the container and is secured 35; as. desired and whereby said container may thereto by a clamp ring 16; The inner edge be removed whenever necessary. v of the annulus overlies a metal disc 17 and With these and other objects'in view which isclainped thereto by means of a clamp will more fully appear, thenatureiof the plate 18. The ,disc 17 is provided with a invention will be more clearlyainderstood filler opening lS from which rises'a filling claims, andthe several views illustrated in to by screw threads, :the neck 19 passing, the accompanying drawings. upwardly through an opening 21 formed in In the accompanying drawings: the clamping plate 18. -Attached to the Figure 1 is a sectional view of a double disc 17 and extendingupwardlythrough an invention, I 18 is astem 23, and to the upper end of this Figure 2 is an'enlarged sectional view of stem is connected a head 24, the stem and the deviceshowing its application to the the head conjointly forming a hand piece. support, v The stem 23 is provided with a passage 25 50 Figure 3 is an enlarged detailed sectional which communicates with the lnterior of spring arm 27 has one end 28 riveted or 7 go bet-ween.

otherwise secured to the wall 13 of the container at a point diametrically opposite the discharge spout 14. This arm 27 extends upwardly and outwardly and thence laterally above the diaphragm and is provided at a point adjacent its free end with an:

elongated opening 28 adapted to receive the stem 28. Clamping nuts 2929 are threaded onto the stem 23 and cooperate with the clamping nut 26 to permit'the arm 27 to have free sliding movements there- The spring arm 27 functions to return the diaphragm to its normal position and also functionsas a handle for the purpose of either carrying the con-I tainer when removed from its support or for swinging the container about its sup port.

In order to removably attach the device tothe supporting standard 7, I have provided a clamp D which consists ofa rigid arm 30 and a spring arm 31. The rigid arm 30 isfixedly secured to the bottom 12 of the container and includes a downwardly extending portion and a laterally extending terminal portion, the latter being provided at its free end with a longitudinally extend ing slot 32. The spring arm 31 normally extends downwardly towards the rigid arm, as shown in Figure 2, and this spring arm is provided with an opening 33 for receiving the head 9 of the supporting standard 7. The width of the slot 32 is just sufiicientto receivethe neck 10 of the standard 7, and" consequently the rigid arm is incapable of vertical movement relative to the standard but is capable of horizontal movement relative thereto.

In practice when it is desired to attach the container to the standard 7, the free end of the rigid arm is guided into engagement with the neck 10, and'simultaneously the spring arm 31 will ride over the head 9 until the opening 33 engages the head 9;

The rigid arm 80 will then become seatedon the shoulder 8 and the flexible arm 31 will cooperate with the head 9 to hold the container against tilting action, either permitting the container to be swung about the standard 7 to any desired position, or to be removed therefrom by simply elevating the spring arm 31 from engagement with the head 9 and moving the entirety towards the left as Viewed in Figure 2.

hen it is desired to dispense the liquid from the container,,the attendant places the palm of his hand upon the head 24 thereby closing the passage 25 from the atmosphere. Pressure is then applied on the hand piece, and consequently the diaphragm will be moved downwardly through the medium of the flexible annulus 15 thereby permitting the air Within the upper portion of the container'to force the liquid outwardly through the discharge spout 14. V This downward movement of the diaphragm flexes the spring, arm 27 and when the attendant releases the hand piece, the diaphragm tends to-returntoits normal position and is assisted in this movement by the spring arm 27. This operation, of course, is repeated as often as it is desired to dispense the liquid;

It is of course to be understood that the details of structure and arrangements of parts may be variously changed and modified without departing from the spirit and scope of my invention.

I claim: Y V

1. In a liquid dispensing device, the coinbinationwith a standard having a head. connected to the upper end thereof by a reduced neck, a liquid dispensing container, and aclamp carried by the bottom of the container for detachable connection with the standard, said clamp including a laterally extending rigid arm having a slotted "free end for receiving the neck of the standard, and a laterally extending spring. arm disposed above the rigid arm and provided with a socket to receive the head of the standard.

2. In a liquid dispensing. device, the combination of a liquid container having an open top and provided with a discharge spout on one side of the container, a flexibl'e diaphragm attached to the top of the container, a hand piece extending upwardly from the center of the diaphragm, the diaphragmand the hand piece being conjointly formed with a passage communicating with the interior of the container and with the atmosphere, and a spring arm connected at one end tothecontainer at a point opposite the discharge spout and at its other end to the diaphragm and. shaped to funccated end of thearm to yieldably engage said knob when in the said bifurcation,

'4. In a liquiddispensing device, a liquid 1 dispensing unit, and means to swivel-mount theunit for rotation about a vertical axis to enable dispensing of liquid 1n various directions, said mounting means compris- 111g" a shoulder-support-equ1pped-standard,

a mounting knob extending above the shoulder-support and joined thereto by a reduced neck, a mounting arm carried by the unit and having its end bifurcated to straddle the reduced neck, and a snap spring carried by the unit and opposed to the bifurcated end of the arm to yieldably engage said knob when in the said bifurcation, said spring having a socket therein to receive the knob and secure the unit agalnst lnadvertent removal from the standard While permit-,

ting'rotative movement of said unit about the axis of the standard.

5. In a liquid dispensing device, a liquid dispensing unit, and means to swivel-mount V the unit for rotation about a vertical axis to enable dispensing of liquid in various directions, said mounting means comprising a shoulder-support-equipped-standard, a mounting knob extending above the shoulder-support and joined thereto by a reduced neck, a mounting arm carried by the unit and having its end bifurcated to straddle the reduced neck, and a snap spring carried by the unit and opposed to the bifurcated end of the arm to yieldably engage said knob When in the said bifurcation, said spring having a socket therein to receive the knob and secure the unit against inadvertentremoval from the standard While permit ting 'rotative movement of said umt about the axis of the standard, sald spring belng projected beyond the said bifurcation and upturned for the purpose described.

In testimony whereof I hereunto affix my signature.
